This course deals with the objects and techniques of astronomical investigation. We will consider planets, stars, and galaxies, with regard to their physical nature, history, and interrelations. Course objectives are:

  • A basic grasp of structure of the Universe
  • How science works - nature is the arbiter
  • Ability to apply this understanding of science to current issues

    Grading and exam policies: The course grade will be based on 11 in-class quizzes (2/3) and a comprehensive final exam (1/3). The worst quiz grade will be dropped in calculating the average grade, thus allowing a single miss with no makeup quizzes (which are done only for medical reasons or because of required absences). Attendance points may be given in conjunction with nighttime viewing sessions during the course, and there will be an opportunity for extra-credit essays. The final exam is scheduled for 8:00 a.m., Thursday, July 3
